NIOSH Warns against Use of Aftermarket Respirator Components

Published March 12, 2014

​A Feb. 27 NIOSH Respirator User Notice warns respirator users against replacing NIOSH-approved respirator parts, components, and accessories with parts manufactured by another company that are not NIOSH-approved. The notice stems from NIOSH’s awareness that some respirator users are replacing the original hoses provided with supplied-air respirators with hoses from different equipment manufacturers—a change that could result in too little or too much breathing air being delivered to the facepiece, according to the agency.

“Because these hoses have not been subjected to the rigors of the NIOSH-approved quality assurance program of the [original equipment manufacturer], they may have other performance features that are not compatible to the proper performance of the respirator,” the notice reads.

NIOSH reminds respirator users that respirators are approved as a single unit and that replacing NIOSH-approved respirator parts with non-NIOSH-approved parts voids the NIOSH approval, which means the same level of performance can no longer be expected.
